Show someone you care about them by spending a little extra time on their Christmas card... and in the process, save some money. In this tutorial, learn how to make a pop-up three-dimensional Christmas card for your loved one.

Step 1: Fold the cardstockFold one sheet of the cardstock in half, making a crease down the middle.

Step 2: Cut two slitsCut two slits, 1½ inches apart, perpendicular to and through the fold. When you open the card, there will be two slits bisected by the fold.

Step 3: Push out the section between the slits and foldPush the strip of card between the slits inward, through the inside of the card. The fold in this section will be opposite the original fold. This is the pop-up mechanism.

Step 4: Make a Christmas treeCut a small Christmas tree shape out of the green paper. This can be done with a simple triangle shape with a stump, or you can get more elaborate and cut out branches.

Step 5: Glue the tree to pop-up mechanismGlue the tree to the pop-up mechanism. When you open the card, the tree pops up in the middle of the card.

Step 6: Add the back pieceGlue the other piece of card stock neatly over the back of the card. This will cover the hole created by the pop-up mechanism and add sturdiness to the card.

Step 7: Add your own personal touchGive the card your own personal touch by adding more artwork or writing a message. There are many different ways to make your card unique, so experiment and have fun.
